The envoys from the three fairy realms have travelled safely and stealthily. This is a good indicator that their mission remains a secret.
Though the rangers are not easily wearied, they are obliged to pass the abode of the Water fairies. It is customary to pay homage to the King and Queen of the realm. Besides, they also need to gather some extra weaponry, for additional precaution in their uncertain mission.
The Blue Haven is situated in the underground grottos of the Azure River. The Azure is a vast body of water filled with a variety of creatures.
This river separates the Earth Haven from the Orange Haven. It serves as a magical barrier that segregates the four realms, with the White Haven above the clouds.
The realms have their individual domains but co-exist peacefully for many, many centuries. It has always been the way the fairies of each realm kept their kind hidden from the human world.
